Another thing to bear in mind...

Those 2.5" drives are under a fair bit more stress than the 3.5" ones, as to get the same storage in a smaller physical space they have to be made to far tighter specs. Generally laptop drives never seem to live as long as normal PC ones.

Nope, it has a mains adapter as it's a 3.5" drive rather than the 2.5" Passport ones (which are also good).

The AF260SA should work but will be seriously limited - you'll only be able to use it manually or by changing the ISO in order to change the aperture. At least, assuming that it works like other Program (before TTL was invented) flashes on a K-m.

Try using the camera in Program mode and see what happens, I know mine takes account of Program flashes when present.

I bought one of the Western Digital "Elements" 1TB drives from Tesco a couple of months ago, no complaints so far. £60 was pretty much the going rate at the time and WD are a known brand, so I thought it worth a try.

I wouldn't fancy an internal 1TB drive as I'm not convinced how long they last if running all the time, however for an external drive which is only connected when I'm backing up data or photos it should be ok.

I don't think there's such a thing as a bad K series lens (the original SMC Pentax range from 1975-77 are often known as the K series). If it's in good condition and the price is fair then go for it. Don't pay more than £50 and for that I'd expect mint or nearly so.

I find stop down metering is accurate down to about f11, go below that and it starts underexposing badly although you can easily meter at f8 then use a bit of simple calculation to set the shutter speed for smaller apertures.

I don't have the 135mm from the K series but I do have the 120mm f2.8, which is a very nice lens indeed. Smooth and solid as all K series and with a nicely unusual focal length.

Just tried that, it seems that I've been using the "wrong" eye all these years!

I usually use my right eye but that test came out in favour of the left.

If my SFX was a bit less heavily used I might well be interested. It's not exactly museum material though with a fair number of rubs and marks around the edges!

Thanks Ken - just done that, and I think it may have cured it! There's currently just over half of a roll of slide film in there so I can't really test it now, but I'm getting continuity between the centre pin of the hotshoe and the centre of the PC socket when I hold the little plunger down. I'll try the flash next time I take it out - it won't make any difference to a daylight landscape shot but that will tell me whether the hotshoe is working.

Slight snag, none of my gear is WR!

I have a roll of Ilford SFX and matched filter awaiting clearer skies. I don't think quasi-infra red photography would be quite as dramatic with dull grey clouds.
